Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an emergency hemostasis auxiliary compression device. Background Art

[0002] Emergency hemostasis auxiliary compression devices refer to medical devices used to control bleeding in emergency situations and are specially designed to assist or enhance the natural hemostasis process. Such devices are intended to be used quickly and easily so that non-professionals can also use them effectively. Common auxiliary compression devices include arterial compression tourniquets, hemostatic patches, mechanical compression devices, hemostatic forceps, etc. In some surgeries such as thoracic surgery, in case of bleeding from large blood vessels, it is usually necessary to roll the gauze into a large ball and press the bleeding location, and then gradually remove the gauze to suture the bleeding point.

[0003] For example, the patent with authorization announcement number CN215739317U, with announcement date of 2022-02-08, discloses a puncture hemostat and a hemostatic system for cardiac puncture. The puncture hemostat includes a first hemostatic membrane and a second hemostatic membrane. The first hemostatic membrane is an elastic body and is used to cover the puncture port. The first hemostatic membrane is provided with a first opening; the second hemostatic membrane covers the first hemostatic membrane at the puncture port and completely covers the first opening. The first hemostatic membrane includes a first state and a second state. In the first state, the first hemostatic membrane is stretched to expand the first opening. The first hemostatic membrane is concave to a certain extent toward the heart, so that a reserved gap is generated between the second hemostatic membrane and the first hemostatic membrane, and the puncture port is exposed. In the second state, the first membrane body elastically recovers and covers the puncture port, the reserved gap is reduced, and the second hemostatic membrane is adhered to the first membrane body to compress and stop bleeding. The cardiac puncture hemostasis system includes a puncture hemostat and a puncture tube, which solves the problem of being unable to monitor pulmonary artery pressure and left atrial pressure in real time after chest closure during cardiac surgery.

[0004] When rolling the gauze into a large ball to assist in hemostasis, the rolled gauze needs to be slowly moved to one side of the bleeding location while maintaining pressure on the bleeding location to make room for suturing. During this process, the gauze also needs to be slowly rolled to change the contact point between the gauze ball and the bleeding location so that the gauze can absorb the flowing blood and the suture location is clearly exposed. This causes the gauze ball to easily spread out during movement and cannot provide sufficient pressure, thereby affecting the hemostasis effect. Utility Model Content

[0005] The utility model aims to provide an emergency hemostasis auxiliary compression device which is easy to move and can maintain the compression force on the bleeding position.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] An emergency hemostasis auxiliary compression device comprises gauze in a closed loop shape and a soft ball. The gauze is sheathed on the outside of the soft ball and is in close contact with the surface of the soft ball.

[0008] The auxiliary compression device has a soft ball in the shape of an ellipsoid, and a gauze in the shape of a hollow ellipsoid with both ends cut off.

[0009] The gauze of the auxiliary compression device includes blood-absorbing gauze and elastic gauze. The blood-absorbing gauze is sheathed on the outside of the elastic gauze, and the elastic gauze is in close contact with the surface of the soft ball.

[0010] In the auxiliary compression device, both ends of the elastic yarn are connected to elastic ropes, the diameter of the elastic rope is smaller than the opening diameter of the elastic yarn, and an annular groove is provided on the soft ball, which is corresponding to the elastic rope.

[0013] The auxiliary compression device is provided with a plurality of supporting members in the annular cavity, and the supporting members are arranged in a circular array around the central axis of the annular cavity.

[0014] The supporting members of the auxiliary compression device include rubber rods symmetrically arranged in the annular cavity, one end of the rubber rod is connected to the middle of the outer wall of the annular cavity, and the other end of the rubber rod is connected to the edge of the inner wall of the annular cavity.

[0015] In the auxiliary compression device, the annular cavity is connected to the cavity through a plurality of air holes, and the air holes are arranged in a circular array around the central axis of the annular cavity.

[0016] The auxiliary compression device has two sets of partitions symmetrically installed in the cavity, and the ends of each air hole are connected to the space between the two partitions.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1-Figure 5 As shown, an emergency hemostasis auxiliary compression device provided by an embodiment of the utility model includes gauze 1, which is in a closed loop shape, and also includes a soft ball 2. The gauze 1 is sleeved on the outside of the soft ball 2, and the gauze 1 is tightly attached to the surface of the soft ball 2.

[0029] Preferably, the soft ball 2 is in the shape of an ellipsoid, and the gauze 1 is in the shape of a hollow ellipsoid with both ends cut off.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, the gauze 1 is a hollow ellipsoid with both ends cut off to facilitate the gauze 1 to be put on the outside of the soft ball 2, wherein the gauze 1 is a disposable consumable, and the soft ball 2 can be reused after cleaning and disinfection, and the soft ball 2 has a strong deformation ability. Optionally, the outer layer of the soft ball 2 is made of silicone material and has a rough surface with a certain friction force, so that the gauze 1 can be better attached to the surface of the soft ball 2; when assembling, pinch the middle part of the soft ball 2 to deform the soft ball 2, reducing the soft ball 2 to Figure 1 The vertical dimension of the drawing is shown in FIG. 1 , and the gauze 1 is placed at one end of the soft ball 2, that is, the soft ball 2 is placed at the Figure 1 Put the left or right end of the view onto the surface of the soft ball 2, and adjust the position of the gauze 1 so that the positions of the gauze 1 and the soft ball 2 are as shown in the figure. Figure 1 As shown, the preparations before hemostasis are completed, and then the middle part of the gauze 1 is kept corresponding to the bleeding position of the patient, and the soft ball 2 is pressed toward the bleeding position. While maintaining the pressure of the soft ball 2 on the bleeding position, the soft ball 2 is slowly rolled to one side of the bleeding position, making room for suture while allowing different areas of the gauze 1 to contact the bleeding position, thereby absorbing blood so that the position to be sutured can be clearly exposed.

[0031] The emergency hemostasis auxiliary compression device provided by the embodiment of the utility model is configured by arranging the gauze 1 into a closed loop, and arranging a soft ball 2 inside the gauze 1 for support. By pressing and rolling the soft ball 2, the space for suturing can be made available, which is convenient for movement while maintaining pressure on the bleeding location. Moreover, the soft ball 2 can also adjust the angle of the gauze 1 while rolling, so that another area of the gauze 1 contacts the bleeding location and absorbs the flowing blood.

[0032] Furthermore, the gauze 1 includes a blood-absorbing yarn 11 and an elastic yarn 12 . The blood-absorbing yarn 11 is sheathed on the outside of the elastic yarn 12 , and the elastic yarn 12 is in close contact with the surface of the soft ball 2 .

[0033] Specifically, the blood-sucking yarn 11 has a strong ability to absorb liquid, and the elastic yarn 12 has a certain elasticity and a stable structure. The blood-sucking yarn 11 is sheathed on the outside of the elastic yarn 12, and the elastic yarn 12 can adhere tightly to the surface of the soft ball 2 after being sheathed on the outside of the soft ball 2, ensuring that the gauze 1 as a whole will not be relatively displaced with the soft ball 2 during the process of pressing and rolling the soft ball 2.

[0034] Furthermore, elastic ropes 13 are connected to both ends of the elastic yarn 12 . The diameter of the elastic rope 13 is smaller than the opening diameter of the elastic yarn 12 . An annular groove 21 is provided on the soft ball 2 , and the annular groove 21 is correspondingly arranged to the elastic rope 13 .

[0035] Specifically, such as Figure 4 and Figure 5 As shown, in order to prevent the gauze 1 from rolling during the soft ball 2, Figure 1 If the openings at both ends of the elastic yarn 12 are offset to the left or right in the view, the elastic yarn 12 will be Figure 1 Elastic cords 13 are provided at both the left and right ends in the view. The diameter of the elastic cords 13 at their original length is smaller than the opening diameter of the elastic yarn 12. In conjunction with the annular groove 21 provided on the soft ball 2, after the elastic yarn 12 is fitted onto the outside of the soft ball 2, the elastic cords 13 return to their original length and snap into the annular groove 21, further tightening the elastic yarn 12 so that the elastic yarn 12 can adhere closely to the surface of the soft ball 2. Furthermore, the elastic yarn 12 is restricted by the elastic cords 13 and will not be offset on the soft ball 2.

[0036] In another embodiment of the present invention, a cavity 22 is provided in the soft ball 2 , and the cavity 22 is filled with spherical particles 3 .

[0037] Specifically, the particles 3 are made of a polymer material. Thus, on the one hand, during the rolling of the soft ball 2, the particles 3 filled in the cavity 22 have a certain fluidity, making the rolling of the soft ball 2 smoother. On the other hand, when the soft ball 2 is squeezed and deformed, its inner wall becomes concave when it is squeezed by the particles 3, and the outer wall of the soft ball 2 correspondingly becomes convex. The tiny convexities on the outer wall of the soft ball 2 increase the friction between the elastic yarn 12 and the soft ball 2, thereby increasing the restriction on the elastic yarn 12 and further preventing relative displacement between the elastic yarn 12 and the soft ball 2.

[0038] In another embodiment of the present invention, an annular cavity 23 is defined in the soft ball 2 . The cross section of the annular cavity 23 is elliptical, and the annular cavity 23 is located outside the cavity 22 .

[0039] Furthermore, a plurality of support members are provided in the annular cavity 23 , and the support members are arranged in a circular array around the central axis of the annular cavity 23 .

[0040] Preferably, the support members include rubber rods 24 symmetrically arranged in the annular cavity 23, one end of the rubber rod 24 is connected to the middle of the outer wall of the annular cavity 23, and the other end of the rubber rod 24 is connected to the edge of the inner wall of the annular cavity 23, as shown in FIG. Figure 2 shown.

[0041] Specifically, during use, the auxiliary compression device is limited by the adsorption capacity of the blood-absorbing yarn 11. Once the blood-absorbing yarn 11 reaches saturation, it will no longer absorb blood. Moreover, since the soft ball 2 needs to maintain the pressure on the bleeding position during the rolling process, and the structure of the soft ball 2 affects the part of the soft ball 2 that contacts the bleeding position, the part of the soft ball 2 that is in contact with the bleeding position is compressed and deformed toward its center point, causing the adjacent position to bulge outward, thereby causing the blood already absorbed by the blood-absorbing yarn 11 to be squeezed outward and flow back to the bleeding position. In this embodiment, an annular cavity 23 is opened in the soft ball 2. The compression deformation of the soft ball 2 only causes the volume of the annular cavity 23 to become smaller, thereby reducing the squeezing force exerted on the blood-absorbing yarn 11 by the adjacent position due to the outward bulge, thereby preventing the blood absorbed on the blood-absorbing yarn 11 from being squeezed out again. The setting of the support member can support the opening position of the annular cavity 23 on the soft ball 2, wherein the outer wall of the annular cavity 23 is the side close to the outer surface of the soft ball 2, and the inner wall of the annular cavity 23 is the side close to the center point of the soft ball 2.

[0042] Furthermore, the annular cavity 23 is connected to the cavity 22 through a plurality of air holes 25 , and the air holes 25 are arranged in a circular array around the central axis of the annular cavity 23 .

[0043] Furthermore, two groups of partitions 26 are symmetrically installed in the cavity 22 , and the ends of each air hole 25 are connected to between the two partitions 26 . Air bags 27 are installed at the ends of the corresponding air holes 25 in the soft ball 2 , and each air bag 27 is located between the two partitions 26 .

[0044] Specifically, since the amount of gas in the annular cavity 23 is constant, when the annular cavity 23 is squeezed and its volume becomes smaller, the air pressure in the annular cavity 23 will increase, which will still cause some areas on the surface of the soft ball 2 to bulge outward. In this embodiment, the annular cavity 23 is connected to the cavity 22 through the air hole 25, and an air bag 27 is provided in the cavity 22 at a position corresponding to the air hole 25. Figure 2 and Figure 3 As shown, when the soft ball 2 is squeezed, the volume of the annular cavity 23 becomes smaller, and the gas in the annular cavity 23 enters the air bag 27 through the air hole 25, causing the air bag 27 to expand and bulge, without causing the surface of the soft ball 2 to bulge outward, thereby further reducing the squeezing force of the soft ball 2 on the blood-absorbing yarn 11, ensuring the good adsorption of the blood-absorbing yarn 11. After the squeezing of the soft ball 2 is released, the air bag 27 recovers, and the gas in the air bag 27 re-enters the annular cavity 23.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
